The Brain and its Lobes

The brain and there functions in way I can understand and make sense of what is going on with our little guy!

Ever since we have found out that Sean suffered a stroke, has a whole in his brain, is having seizures I have been trying to figure out what lobes are effected and what each lobes function is inside the brain. Here is what I have figured out after spending tons of time on the internet.

Sean’s stroke happened in the parietal lobe and this is what I was able to find out:

It is located above the occipital lobe and behind the frontal lobe. The parietal lobe integrates sensory information from the different senses, especially spatial sense and navigation. The parietal lobe plays important roles in integrating sensory information from various parts of the body. The parietal lobes can be divided into two regions one involves sensation and perception and the other is concerned with integrating sensory input. The first function integrates sensory information to form a single perception (cognition). The second function constructs a spatial coordinate system to represent the world around us. Individuals with damage to the parietal lobe often show striking deficits, such as abnormalities in body image and spatial relations.


And of course the best part is much less is known about this lobe than the other three in the cerebrum. Great thanks. I know that there is still so much to learn about the brain. But don’t researchers and doctors know that we need to know more about all lobes but I NEED to know more about this one. My unborn baby had a stroke and it affected this lobe (well it affected three lobes…but occurred in this lobe) Okay enough said above since there is not much out there on the parietal lobe.

Let’s move to the frontal lobe. The frontal lobe is located at the front of each cerebral hemisphere and is in front of the parietal lobe and above the temporal lobe. It is separated by the primary motor cortex from the parietal lobe. So this makes sense of why the frontal lobe is affected from the stroke. The function of the frontal lobe involves the ability to recognize future consequences resulting from current actions, to choose between good and bad actions….. aka behavior. The frontal lobe are considered our emotional control center and home to our personality. The frontal lobe are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social behavior. The frontal lobe are also thought to play a part in our spatial orientation, including our body's orientation in space. This makes sense since Sean has body space issues.

The last lobe affected by the stroke and everything else is the temporal lobe. This is also where Sean is having seizures at. The temporal lobe involves speech, memory, and hearing. It is highly associated with memory skills. Seizures of the temporal lobe can have dramatic effects on an individuals personality. Temporal lobe epilepsy can cause aggressive rages. Lets hope that this is not the case for Sean.

If anyone is interested in learning more I got most of my information from the following websites.

Hi,I have a 22 yr.old daughter who has closed-lip schizencephaly.We did not find out until she was 5.She also has Cerebral Palsy on her left side.Luckily its not very noticable.She also has a eye problem,which isnt noticable.She has had 3 major ear surgeries for Mastoidectomy.Of course its the ear on the side of her Cerebral Palsy.She has never had seizures but has episodes of shaking if she gets really upset,but,the Dr.said its not seizures.I would love for her to meet someone around her age so she could talk & they could relate with each other!!!please e-mail me at aprillynne123@msn.com THANKS
